showl hanged rirn can be expanded and locked on the inner face of otherpneumatic or solid types of tires.

A further function of the clencher rings 3C is to prevent the rupture ofrim '7, at its joint orq elsewhere, by centrifugal force when the wheelis rotating'at a high speed.

Upon the felly 3, a metal band lis shrunk, which is provided withoutwardly and-upw wardly projecting flanges 5 and 5A, at its oppositeside edges, shown in Fig. 1l. These flanges however are cut awayabovethe locking bolts 6, and this band at and adjacent to these bolts is astraight Hat band, as shown in the section in 9 and l0. Upon the flangesof this felly band, l mount loosely a tire supporting rim 7. Thisriin 7comprises a iat metal rini, that is provided at its opposite edges withraised flanges 8 and 3, both of which extend circumferentially aroundit, and a fiat channel portion 9A is formed between the flanges 8 and 9.This riin is a circular channeled rim that may be divided transverselyinto one or two or more pieces,' as desired. l preferably illustrate itdivided transversely at only one point in its circumference by a cut 10.This cut 10, is preferably an oblique cut to the radial diaineter of therim, and is preferably made at an angle that permits the meeting ends lland .l2 to slightly overlap each other. At this divisional transv rsecut, the rim is provided with a circular concave-convex cup i3, one-halfof which (see Fig. fl) is formed in each meeting edge of the rim, and inone side of this cup a dish-shaped nut 14, is secured, the upper surfaceof which is even with andvis concentric with the curve of the peripheralsurface of the rim. rlfhis disk is preferably secured to the one halfpart of the cup that is in one end of the rim, by rivets l5, and thisdisk is preferably riveted to the half cup portion of the "beveled endthat laps over onto the beveled edge of the other end of the rim. intothe half part concave-convex cup that forined inthe opposite end of therim, and ts snugly into it when the meeting ends of the riin are closetogether, and through the arial center of this disleshaped nut a threadled aperture 16 is formed, which is adapted -to. receive a threaded studportion 17, that is formed on the inside of a concavcconvex cap 18 (seeFig. 5), which l terni the locking cap, and which is adapted to tit overthe two divided halves of the cup i3 (see Figs. 8 and rllhis cap isscrewed into' the threaded aperture in. the dislrsliaped nut, and onto.the two half parts of the divided cup, and

locks the two halves of this concave-convex iup and also the two endsor" the rim rigidly together, in a true circle (see Figs. 2, l5 and 8).This locking cap is provided with apertures i9, which are adapt-ed toreceive theV ends ci any suitable Spanner wrench to as- This disk 14projects over sist in turning the cap and screwing itup tightly on thecup. rllhe rini is also provided with a plurality of similarccncavoconvex cups 20, throughout its circumference, and they are spacedpreferably at equal distances apart, and they are also preferablypositioned in the center of the width of the channel portion of theriin. They are 'preferably pressed or stamped in the periphery of thecircumferential surface of the rim,

although if desired they may be rolled or otherwise formed in the rim,or may be made independently of it and be secured to the riin by anysuitable means. llach of these concave-convex cups forms a dependinglocking lug that is employed coperatively with locking plates 21, andthe locking bolts t3, to lool; the riin rigidly to the felly band andfelly, and they are arranged and adapted to rest on thejpcripheralsurface of the felly band loosely when the riin.

is locked together and is mounted on it. Each of these concavo-convexlocking cups is iilled up flush and even with the peripheral'surface ofthe channel surface of the rim, in order that the inner peripheralsurface of the tire may have an evenly curved and solid bearing surfaceon the entire.cir culnferential surface of the rim, and while there area number of ways in which these concaved recesses of these cups may befilled up, l preferably carry out this feature of my invention in thefollowing manner: ln each one of these concave-convex cups 20 I placeand lit latdisk shaped metal plate 24, on the under sideof which anaxial lug portion 25, is formed, that rests against the central portionof the bottoni of each cup, through the center of which an aperture 2Gis formed,

through which a riveting terminal end portion 27 of the lug 25 projects,'and is securely riveted therein and vto the apertureV in the cup, whichis countersunk on the outs1de to receive it (see Figs. 9 and 12). The

outer surfaces of these disks are made even and concentric with theperipheral surface of the channel portion of the riin. The cup 22,through which the air inlet tube 23 is cxtended, instead of beingprovided with a metal plate disk, is provided with a flexible Washer 28,of rubber orleather or other suitable material. I preferably, however,use a iic rubber Washer, which preferably iits tight y enough on the airinlet tube to be lifted out of the cup when'the rim is collapsed andlifted off from the tire. This rubber washer 28 is also made to fit andfill the cup flush with the peripheral surface of the rim. The bottom ofthis cup 22 is also provided with an aperture 29, through which the airinlet tube extends loosely, and an aperture 30 is extended down throughthe felly band and the felly, through and beyond which the air inlettube 23 projects loosely in a manner conunonv to automobile Wheelshaving pneuintrede lnatio tiros, streven in 10v The inner `peripheralsm'l'ace olf the run adjaeent to its ends an l'd, pre led at slioiftdistance from each ond el the riin with a pair ot depending lugs F A,vvlncli nreiii-frsbly are of deve-tailed rin and are placed and used tocollapse and also to spread the en i of the .rim by ineens any suitablesgoanner wrench, when deinem. and detacliinig it `trom the 'telly andtire tire, as will be t'ulljv described here-- i fils e Y Y e' esV)revided with` a i-cnfcular .ree lll.

Thelocking vplates that are on the inner side 3l' ol the wheel, arepreferably provided with outwardly,7 inclined slots 3S, on 'the oppositesides ot' their outer edge, which are positioned to lit down looselyover the adjacent ends 39 ot the side flanges of the telly bands, asshown in Figs. (l and '.llicse side 'langes ot the telly band are asbefore stated, out away at the points of the felly band Where theselocking plates are positioned. These ends iQ-are arranged to' projectinto the slots 38. This arrangement secures the inner locking platesagainst ae cidental displacementfrom the telly when the nut is removedfrom its locking bolts. l preferably illustrate a section of anautomobile Wheel showing three oit these locking plates and implying;that six would preferably be used in theI Whole wheel, but more or lesshowever, can be used as desired.

The rirn 'i et' my improved demountable tire apparatus is adapted toreceive und support either pneumatic or solid tires. l

Ihave, however, preferably illustrated it provided with a pneumatic tire3, of the clenclier type, in Figs. 9 and l0, and with a straight sidetire, in, Fig. l5. The side rings 3C are of the commonly used type andare provided, illustrated, with a rabbetecl step l2, that permits themto tit over the top edge of the side flange lugs of the rim, and theyare provided With a Wide irm bearing surface on the channel surface ofthe rim. liLF .15',-tlie flanges 40ct the rim are extended upwardly arenough to support this straight sided forni ol tire, and at theirterminal. edges are flared outwardly.

ln Fig. l l, l illustrate a sliflit nioditication of my locking deviceoit the divided split rim/,Tin which the air inlet 'tube is extendedthrough tbc locking' device ot the meeting ends of the collapsible rim.To accomplish this l provide the projecting stem of tlie cap 'with anaxial aperture 44%, the interior surface of which is threaded, and stillleave in the cup the disk-shaped Washer tlirougli which the metal airinlet tube of the inner tube of the pneumatic tire projects, and thismetal air inlet tube''s ei;- teriorlv threaded and tbe. concave-convexlocking rap threads over and onto it and' draws the divided parts o theconcaveconveX cup and the meeting; ends of the rim together as thelocking' nut on tbe -inetal air inlet tube is drawn dori'n and restsagainstthe top of tbe disk-shaped washer in the split cup.

The operation ot my (lcinolmtable tire supporting riin is follows: Forillustration, l take a rnieurnatic clenclicr lire and then: First, placet-lie metal rings loosely or coment thorn onto tlie clcnclier beads ofthe lire. Put tbc .round rubber washer on the valve stein Otau innerlube, andA place lll() the tube in the tire. Take my flanged rim in itscollapsed state, as shown in Fig. 3, and place it within the circle ofthe tire and metal rings, with the valve stem of the lube passingthrough the hole in the center ot' one of the concavo-convex cups of therimVY adapted to receive it. Then expand my flanged rim with suitabletool to form a true round circular rim as shown in Fig. 2, against theinner periphery of the tire and metal rings. Then lock the meeting endsof the rim together by screwing-en ...tlie locking cap over theconcave-convex cup'at' the meeting end of the rim, thus holding the rimrmly and securely iiit-liis inner and side supporting position in thetire and rings. The tire is now firmly secured to the rim and is readyto be inflated with air pressure. Second, to place the inflated tire andsupporting rim on the vehicle wheel, turn the wheel in a position withthe valve stem hole on top. Then put the valve stein in said hole andswing lower part of the tire rim on against the fixed or permanenthalves of the locking plates of the telly band. Then place the loosehalves of the -permost; pull the lower locking plates over the tellybolts and around the cups of the rim between the rim and telly band'.Then screw the nuts o n the bolts and against the locking plates andforce them tightly .around the depending cups of the rim, thus securingthe rim rigidly to the telly.

To demount the rim and, its tire, remove the nuts from the locking boltsand then the locking plates and then turn the wheel until the air tubeis up- )ortion of the rini and the tire from the elly; then raise theupper portion of the rim and the air tube out of the telly. Then todetach the deflated tire from the rim, first unscrew and remove thelockingV cap from the concaveconvex divided cup at the joint of themeet- 'ing ends of the rim; then insert any suitable spanner wrenchbetween the depending lugs on opposite sides ot the joint, and springthe ends apart and one below the other, which allows the riin tocollapse smaller in diameter, as shown in Fig. 3, and moves it away fromthe tire and its metal side rings, and the riin can then be lifted outfrom within the inner periphery of the tire and its metal side rings.

The operation of mounting a iiat sided tire onthe riin is substantiallythe sanie as for a clencher tire.

The essential --features of my invention consist in the transverse cutjoint or joints in the tire riin held rigidly to resisttlie collapsingpressure of air in the inflated tire cavo-convexl threaded locking captting over the divided parts of this divided cup and the screwing intothe threaded aperture of the disk; also the recessed and concavedJforinlocking plates that extend across the telly'band underneath therhin-end surround the depending concave-convex cups of the rini, whichare rigidly bolted to the telly, which owing to their even and'rigidbearing against the full circular surface ot the dependingccncavo-convex cups of the rim, do not distort the round diameter of therim from a true circle when the rim is rigi ly secured to the peripheryof the telly band. Theseeoncavo-convex cups serve three dirtinctpurposes'as' follows: ljirst, to provide a means for locking themeeting-ends of the rim together; second, to provide means tor lockingthe rim to the Jelly band; third, to provide a recess for a flexiblewater resisting washer through which the air inlet tube projects.

My invention is simple in construction and provides a quicklydeinountable rim from both the telly and the tire, and while l haveillustrated and described the preferred c'onstruction and arrangement ofmy invention, I do not wish to be limited to it, as changes might bemade in its construction without departing from the spirit of myinvention.

Having described. my invention, what I claim as new and desire to secureby Let-ters Patent, is:

l. A demountable tire supporting rim, comprising-a collapsible rimdivided transversely by a cut and provided with meeting ends at saidcut, and means including a two part concave-convex cup depending Jfromthe inner peripheral surface of said rim at its meeting ends, aconcave-convex cap fitting over said two part cup and arranged to locksaid parts of said cup and the meeting ends of said collapsible rimtogether.

2. A dem'ountable tire supporting rim for the purpose specilied,comprising a rim arranged to collapse to a smaller diameter, and havingmeeting ends arranged to form circle when in alinement together, andmeans including a depending concave-convex cup and a cap for locking themeeting ends of said rim together.

3. A deinountable tire rim or'the fellies of automobile and otherwheels, comprising a rim, a plurality of depending concaveconvex cupsspaced apart around the inner periphery of said rim, and means includinglocking plates bolted to the opposite sides of said telly and arrangedand adapted to inclose and be clamped around and .against said cupswhereby said rim is demountably secured to said telly.
